From: Seiji Munetoh <[email protected]> Change the binary output format to actual ACPI TCPA log structure since the current format does not contain all event-data information that need to verify the PCRs in TPM. tpm_binary_bios_measurements_show() uses get_event_name() to convert the binary event-data to ascii format, and puts them as binary. However, to verify the PCRs, the event-data must be a actual binary event-data used by SHA1 calc. in BIOS. So, I think actual ACPI TCPA log is good for this binary output format. That way, any userland tools easily parse this data with reference to TCG PC specification.
